DEEP-WELL PUMP.-

To all 'whom t may concern.' Y

Be it known that we, 'I-IEEBER;` J. VVOOCK and WALTER R'. Wooox, both citizens of the United States of America, and residing at Lodi, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in l Deep-Tell Pumps; and we do declare the following to be a' clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in pumps and particularly to a type adapted to be installed in a well in spaced relays, bel ing an improvement over that type shown in our copending application for patent Serial No. 255244, filed September 23rd, 1918.

The vprincipal object of the present invention is to provide pump units installed in a well casing at spaced intervals therein inl such a manner that all weight of water and metal is taken off the driving. shaft, thus reducing friction and tensional strain on`the shaft to a minimum.

By the use of our pump, water may be raised from any depth by placing a pump unit inthe well about every twenty feet, all the units being operated from the one drive shaft, but each one being mounted independent from the others. v

We have also provided means whereby any inaccuracies in the lengths of the pipes connecting the various units will be com pensated for without 'the necessity of making any adjustments in the pump unit affected.

A further object is ,to provide a lubricating system for such units which will be positive in its action and by means Ofwhich all the wearing and running ,parts ofthe-units will be automatically lubricated without attention on the part of the pump' operator..

A still further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for. the purposes for which it is desi ned.

hese objects we accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

Specification of Letters Patent. i Patnted luay 18, 1920. Application filed- April 24, 1919. serial No. 292,515.

On the drawings, similar characters of parts in F ig. 4 is a cross section taken on a line 4-4 of Fig. 1.

Referring now more particularly to the gures of reference on the drawings, the numeral 1 designates a casing member threaded in-its upper end, as at 2, for the reception of a length of plain pipe therein.

This casing is vprovided with vanes 3 running vertically therein and for the greater part of their length'are radial from a tubular hub'4 formed integraltherewith. At their lower ends these vanes turn down at a suitable angle as at 5, such angledl ends terminating at the bottom of the member 1.

Turnably mounted in the hub 4 andbearing against a shoulder 6y projecting inwardly therefrom is a .sleeve 7 having spline-ways 8 cut on the inner face of-theupper end thereof for a certain distance to receive the lower splined end 9 of a shaft 10 which extends upwardly to the motive power running the' pump or `to an upper `is inclosed in an integrally formed casing 15 projecting abovek the same as at 16, this latter portion having a ruiming it on its inner face with the outer face of the lower end 17 Of the member 1. The pitch of the spirals 14 is the opposite to that of the angled portions' 5 of the vanes 3.

Theupper end of the portion 16 has an outwardly projecting flange 18 thereon,vthe casing 1 above-the same extending slightly ,beyond the edge of this flange.

.i This flange rests on a ball bearing 19 mounted in a casing 2() threaded to the casing 1 at its upper end, as at21, the outer.'v

face of the casing -being a running fit against the inner face of the casing 20. The member. 2 9 lisrcored out below the ball race 19 to form a reservoir 22 for a purpose as will appear. l 1 e Threaded into the lower end of the casing 20, as at 23, is a lower casing '24 having its' lower end threaded, as'at`24a, for connection. with "a plain pipe. Threaded into the member 24 and abutting against the lower edge of the runner member 14 is-a casing 25 having a hub 26 thereon similar in shape and construction to the hub 4 and being con,-

nected to the casing 25 by webs 2T. Thelower end of the sleeve 7 which terminates 1nthe hub 26 is 'provided with splineways 128 to receive the uppery end of a spline shaft 29 which extends downward to the pump lunit below.. The lower end of the casing 24 is'threaded internally as at 29 for the connection of a plain pipe thereto. l,

The shafts 10'and 29 are inclosed for their entire lengths by means of tubes 3() placed f hole 32 through the sleeve 7, thus admitting the oil intoA the interior `of the sleeve T. From this point some. of it passes down/to lubricate the lower shaft 2S through a groove 33 cut adjacent one of the splines of the said shaft, while a portion vof the oil.

partially filled with oil.

which'would run slowly down the walls of the interior of the sleeve?, is forced by lthe centrifugal action of the. turning of the sleeve through an orificel 34 suitably positioned therein an'd"cmmiuiic'ating with an orifice 35 in theV runner 1 4 and extending up through the casing 16 and out through the flange 18. Here it empties into a pocket 36A in the casing 20 which has a vertical orifice 37communicating with the reservoir 22, also The oil from this reservoirisraised through the orifice 37 to the level of a passageway 38 from the said orifice to the ball race 19 by means of a spiral conveyer 39 positioned .therein and having a cone 40 on its upper end adapted to bear against the beveled face 41 of the flange 18 and be rotated thereby. The overflow from the ball race and orifice 35 passes back into the reservoir 22 through a passageway 42.

Thus, it will be evidentthat a continuous and complete circulation of oil is maintained against all wearing and friction surfaces.

In the form of runner shown in Fig. 3, the casing 15 is done awa-y with, the spirals 14a bearing directly against the sides of the casinfr 1 extended -downwardlv forthe ur-" pose. This type of runner is adapted to be used forlow heads and pressures only, the

runner member being keyed directly to the pump shaft and the weight carried thereby,

and also the ball race 19 will be dispensed.

with, as shown in our Icol-pending` application hereinbefore mentioned. In operation, supposing water, etc., to be pumped from a deep well, one of these pump units is-interposed in the pipe 'line at suitable intervals .e

therein, usually about vevery twenty feet.

By means of our .improved runner mounting construction, no weight is carried on the pump shafts, as each runner rests on its ball race independent of the shaft, which has an allowance for vertical sliding motion in the spline ways of the sleeves 7 should such be necessary for any reason, such as a short length of pipe between any two units, etc.

The unit at the bottom of the well of course has no shaft 29 therebelow, thesleeve 7 being plugged up to prevent any water getting therein.

Thus, from the foregoing description it will readily be seen that we have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the .present and preferred construction tions from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
